#pyb_DMX This module tries to make it slightly simpler to send DMX512 messages to lights Here is a very simple example of how it works, ideally ```write_frame()``` should be done on a timer interrupt as DMX lights expect a regular message ```python # create a dmx device on UART port 1 dmx1 = dmx.universe(1) # Set the channel(s) to the value you want DMX1.set_channels({1:i}) # Send the message DMX1.write_frame() ``` thanks to this website for useful details [http://www.ubasics.com/DMX-512]
